Abstract
The present invention relates to an asynchronous access system for accessing a shared storage in a multiprocessor system in which a plurality of processor modules and shared storage modules are connected through a system bus. The present invention accesses the shared storage at a high speed and reduces the overhead of the system bus. The present invention recognizes in write and read instructions serial access addresses of the shared storage, requests a block access in which a predetermined number of words are grouped as one block, and performs a recovery process when a write instruction is executed abnormally in the block access.
